To all whom t may concern:

In my drawings, A represents the bolster, and B the transom. These are made of pressed steel of. the general shape indicated. The bolster A in the process of pressing is 4shaped so as to have a center plate C,with

an opening therethrough, formed of the body ot the metal itself, and the transom B has a similar re-entering part iitting the center plate of the part A, pressed in the operation of making the same. Openings for the passage of the king-bolt are provided through these parts. In addition pressed-steel wearing-plates D E are provided, attached to the parts A and B and taking up any wear at those points. The transom B may be strengthened at the bottom by transverse plate F, if desired, and bearing parts G H, likewise of pressed steel, may be attached to the ends of the tran som and beam, as shown. These parts K are all made by preference of pressed steel of the shape shown, and the parts D, F., G, and H are made to tit the shapes of the parts A and B, as indicated.

What I claim as my invention, and desire 3. The combination of a bolster-beam and transom, each being hollow and having center plates pressed therein in process of manufacture, substantially as described.

4. The combination of the beam'A, wearing-piece D, transom B, and Wearing-piece E, all of pressed steel and fitted to each other in process of manufacture, substantially as described.

` 5. The combination of the bolster A and transom B, each having re-entering vprojections pressed therein in process of manufacture, and the parts G and H, engaging with each other, substantially as fdescribed.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses'.
